[0021] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0022] Example:

[0023] like Figure 1-Figure 3 As shown, a welding positioning tool for an automobile body includes a mounting base plate 1, connecting legs 2 are symmetrically provided on the outer side of the edge of the mounting base plate 1, a lifting mechanism 4 is symmetrically provided on the top of the mounting base plate 1, a lifting mounting plate 5 is movably connected to the inner side of the lifting mechanism 4, and a clamping and flipping mechanism 6 is fixedly connected to the top of the lifting mounting plate 5.

[0024] The working principle of the above technical solution is as follows:

[0025] During use, the automobile shell can be positioned and fixed by the clamping and flipping mechanism 6. After welding one side of the automobile shell, the height of the lifting mounting plate 5 can be raised by the lifting mechanism 4, thereby driving the clamping and flipping mechanism 6 and the automobile shell to be raised. Then, under the action of the clamping and flipping mechanism 6, the automobile shell can be flipped, and the other side of the automobile shell can be quickly raised, which is easy to operate.

[0026] In another embodiment, if Figure 2 As shown, the lifting mounting plate 5 includes a fixed support frame 7, the inner top end of the fixed support frame 7 is fixedly connected with a connecting mounting top plate 8, the top of the connecting mounting top plate 8 is fixedly connected with a fixed mounting frame 9, the top of the fixed mounting frame 9 is fixedly connected with a first servo motor 10, the output end of the first servo motor 10 is fixedly connected with a driving gear 11, the end of the connecting mounting top plate 8 is movably connected with a threaded rod 12, and the top of the threaded rod 12 is fixedly connected with a driven gear 13.

[0027] The first servo motor 10 can drive the driving gear 11 so that the driving gear 11 drives the driven gear 13 and the threaded rod 12 to rotate when rotating. At this time, the lifting mounting plate 5 can be lifted and moved outside the surface of the threaded rod 12 to adjust the height of the clamping and flipping mechanism 6 and the car body.

[0028] In another embodiment, if Figure 2 As shown, the bottom end of the threaded rod 12 is fixedly connected to a connecting bottom block 14 , and a positioning sleeve 15 is movably sleeved on the outer surface of the connecting bottom block 14 , and the bottom of the positioning sleeve 15 is fixedly connected to the top of the mounting base plate 1 .

[0029] When the threaded rod 12 rotates, it can drive the connecting bottom block 14 to rotate inside the positioning sleeve 15. The positioning sleeve 15 can limit the position of the connecting bottom block 14, thereby limiting the bottom end position of the threaded rod 12, which is easy to operate.

[0030] In another embodiment, if Figure 2 As shown, the lifting installation plate 5 is connected to the threaded rod 12 via threads, and the outer side of the end of the lifting installation plate 5 and the inner side of the fixed support frame 7 are slidably fitted with each other.

[0031] The installation plate 5 can be stably lifted and lowered on the outer side of the threaded rod 12 and the inner side of the fixed support frame 7, which is easy to operate.

[0032] In another embodiment, if Figure 2 As shown, the driving gear 11 and the driven gear 13 are meshed and connected with each other.

[0033] This facilitates stable transmission between the driving gear 11 and the driven gear 13 .

[0034] In another embodiment, if Figure 3 As shown, the clamping and flipping mechanism 6 includes a second servo motor 16, the output end of the second servo motor 16 is fixedly connected to a fixed connecting plate 17, both ends of the fixed connecting plate 17 on a side close to the second servo motor 16 are fixedly connected to electric telescopic rods 18, the output end of the electric telescopic rod 18 is fixedly connected to a movable clamping plate 19, and a fixing groove 20 is opened on one side of the movable clamping plate 19.

[0035] The electric telescopic rod 18 can push the movable clamping plate 19 so that the movable clamping plate 19 clamps and fixes the car body. The edge of the car body can be stuck in the inner side of the fixing groove 20, thereby clamping and fixing the car body. At the same time, the fixed connecting plate 17 can be driven by the second servo motor 16 to drive the electric telescopic rod 18, the movable clamping plate 19 and the car body to flip over, thereby turning over the car body.

[0036] In another embodiment, if Figure 1 As shown, a fixing pad 3 is fixedly connected to the middle of the top end of the mounting base plate 1 .

[0037] When the automobile shells have not been welded, the connection between the automobile shells can be detached by the fixing pad 3, so that the edge of the automobile shell located inside the fixing groove 20 and the connection between the automobile shells are at the same level, so that welding can be carried out stably and the operation is convenient.

[0038] The working principle of the utility model is as follows: during use, the automobile shell is placed on the top of the mounting base plate 1, so that the connection between the automobile shells is located on the top of the fixed pad 3, and the electric telescopic rod 18 pushes the movable clamping plate 19 at the same time, so that the edge of the automobile shell can be stuck in the inner side of the fixed groove 20, and one side of the automobile shell is welded. After the welding of one side is completed, the first servo motor 10 can drive the driving gear 11, so that the driving gear 11 drives the driven gear 13 and the threaded rod 12 to rotate when rotating, and the lifting mounting plate 5 can move upward on the outer side of the surface of the threaded rod 12, so as to drive the second servo motor 16, the fixed connecting plate 17, the electric telescopic rod 18, the movable clamping plate 19 and the automobile shell to move upward, and then the fixed connecting plate 17 is driven under the action of the second servo motor 16, and the electric telescopic rod 18, the movable clamping plate 19 and the automobile shell are turned over, so as to turn over the automobile shell, so as to weld the other side of the automobile shell, and the overall structure is simple and easy to operate.

[0039] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
